GOP presidential hopeful Newt Gingrich came under sustained attack on Wednesday for a radio ad which labelled rival Mitt Romney as "anti immigrant". The ad was criticised by Republican Senator Marco Rubio, tipped as a future vice-presidential nominee, and many other Hispanic political leaders in Florida. Rubio said the ad was "inaccurate, inflammatory and doesn't belong in this campaign". On Wednesday afternoon, the Miami Herald reported the controversial ad had been "pulled". The video above, from an unverified account, appears to have put the audio to images. A previous Gingrich ad in Spanish was posted on this channel and linked back to an official Gingrich website Newt Presidente.com. There are 450,000 Hispanic Republican voters in Florida; making them key in the Romney and Gingrich battle for the state on January 31.
